8-inch cavities with higher Q-factor are used when duplexer, assembled on 5-inch cavities, unable to provide appropriate isolation because of low frequency separation TX/RX.
Increase in the number of cavities (in duplexer DPF8-6V case) leads to gain slope increase and to decrease of receiver desensitization.
